Of course I came home tonight and the amp sounded fine. So it seems to be intermittent.. so I walked away from it for awhile with it powered up.. came back to it ,cranked it .. sounded great. shut it down, had dinner.. powered it back up and the noise returned, so I probed for an hour or so with a chopstick.. every solder joint.. the amp didnt make a peep.. so I decided to pluck one string at a time at full volume.. and the bottom end.. on the E and A string I could here a loud sizzle that would come and go as the note rang out.. Definetely did not sound like vibration.. was def and electronic noise of some sort. Im wondering if I have a bad resistor someplace.

Cheers and thanks again for your comments
